To all whom it may concern:

Be it known that I, STEFFEN MtiHL, a subject of the King of Denmark, residing .at Classensgade17, Copenhagen, Denmark, have invented new and useful Improvements in Underframes for Vehicles of Any Kind, of which the following is a specification.

The present invention relates to suspension systems for motor vehicles, and particularly motor vehicles of the character. in

i 1 which only onepair of springs is provided for two axles, the object of the invention being to provide a suspensionsystem by means of which the axles will have a greater range of vertical movement and the suspending action of the springs will be generally improved.

In devices of this character as heretofore constructed, the springs were disposed on, a shaft journaled on the frame of the vehicle in such a-manner that the range of vertical movement depended entirely uponthe elasticity of the springs. By means of the present improvement, however, the axles are caused to have a vertical movement which is entirely independent of the resiliency of the springs, whereby the cushioning effect of the springs is considerably improved.

a lustrated in the accompanying.drawing,.in.

which- Fig. 1 shows a motor vehicle in side elevation,

front wheels being hinged to the said ax1es.-

i The intermediate wheels 1' are supported by an axle m, which is the driving axle,

c'Irivln-g wheels, and may be braked in ordmary manner. The axle 'm; is attached to One embodiment of the invention is ilso that the intermediate wheels become the two carriage springs '05, the front ends of which are pivotally connected to across bar I) attached to the frame of the chassis. The rear end of .each spring a is hinged to the front end of a two-armed lever d, one such lever being provided on each side of the frame 9, to which the levers are ivoted by means of. pins 07.. The axle fof t e rear wheels is attached to the rear ends of the levers d, in such a manner that a rigid frame is formed by the two levers and the rear-wheel axle, the said frame being thus pivotally connected to the chassis frame by means of the pins n and hinged to the rear ends of the springs of the intermediate wheels. I

In the frame formed by the levers d and the rear wheel axle f there are provided two diagonally disposed stays p of round iron, the front ends of which are connected to the levers d at a point near the hinge ter are attached to the rear wheel axle.-

These crossing diagonal stays serve to take up any forces acting in the transverse direction of the frame, whereby any torsional effects on the pins or. will be avoided.

Having thus described my invention what I claim is v Asuspension system for motor vehicles, comprising, in combination, a vehicle frame, -a pair of laminated springs each connected at .one'end to said frame, a frame-shaped lever pivotally securedapproximately at the center of its length to the vehicle frame and connected at one end' to the free ends of said springs, a wheel axle carried bysaid lever at its opposite end, and a wheel axle carried by said springs approximately midway of their length.

In. testimony whereof'l have signed my name to this specification.
